10:46 Mechanics of Deform... ← CE104.2T.24.25. FA 1 5 of 6 2.5/10 Rigid bar ABCD is loaded and supported as shown. Steel [E=27800 ksi] bars (1) and (2) are unstressed before the load P is applied. Bar (1) has a cross- sectional area of 0.83 in.² and bar (2) has a cross- sectional area of 0.45 in.2. After load P is applied, the strain in bar (1) is found to be 670 με. Assume L₁=58 in., L2-94 in., a=26 in., b=22 in., and c=36 in. Determine: (a) the stresses in bars (1) and (2). (b) the vertical deflection VD of point D on the rigid bar. (c) the load P.
